User-driven GIS software reuse solution based on SOA and Web2.0 concept

The development and application of the traditional GIS, as a platform, have long been heavyweight, expensive and non-public. Nowadays, with the explosion of Web2.0, they are facing challenge. An agile, lightweight, reusable GIS is now in need. This paper promotes a solution to meet this need. Based on SOA, the solution fulfills the concept of Web2.0 and software2.0 and designs an open architecture on the service components and widget level. It divides GIS development into two parts: the part of service component and widget development, and the part of mashup. The prototype and example prove that this architecture can make GIS development more agile and lightweight, while making GIS application more public.
